The first domestic and the world's largest and largest high-power electric locomotive dynamic test rig has been inspected by Tianjin Electric Locomotive Co., Ltd. (Tianjin Locomotive Company), and has been officially put into use. This test rig was built by CNR Dalian Locomotive Research Institute Co., Ltd. (China CNR Dalian Institute).
This test bed has a single-axis power of 1600 kilowatts and a maximum operating speed of 220 kilometers per hour. It is currently the world's largest locomotive dynamic test bed with the highest power, the highest technical level, and the most advanced performance indicators. It can replace the currently widely used high-power locomotive. Electric locomotive factory line test. This means that the newly developed electric locomotives do not have to go to the busy railway line afterwards, and only need to complete a routine "physical examination" during this period to measure the hard performance indicators such as their operating performance in different operating environments. This test bench can meet the performance test needs of high-power electric locomotives in China, and can be used for the first time to replace the high-power AC drive electric locomotive factory line test in combination with the factory test operation line, effectively solving the current locomotive line test operation difficulties and serious interference The issue of railway transportation order is a hallmark of the new generation of locomotive dynamic test bed for railways in China.
This test bench takes full account of the extreme environment of electric locomotives and builds test benches to a high standard. For example, its maximum operating speed is 220 kilometers per hour, which has reached the operating speed of high-speed EMUs, while the maximum speed of electric locomotives currently operating in China is at most 160 kilometers per hour.
The test bench has high complexity, wide coverage, and is difficult to design, manufacture, and construct. Based on its experience and technology accumulation in the design, manufacture and application of vehicle dynamic test benches, the Dalian Institute combines its advantages in network control, variable current control technology and electric drive system integration with China North Vehicle Dalian Electric Pull R & D Center. , Manufacturing and integration, with completely independent intellectual property rights. After the individual commissioning and joint commissioning of the various systems in the early stage, the HXD3 locomotive provided by Tianjin Locomotive Company was used to carry out the operation evaluation and functional verification of the test bench. From the data collected and the functions realized, the expected results were achieved and obtained Recognized.
When this electric locomotive vehicle dynamic test stand is put into use, it can not only effectively improve CNR's own locomotive research and development capabilities and inspection methods, but also undertake related businesses.
Tianjin Electric Locomotive Co., Ltd. was jointly established by CNR, Beijing Railway Bureau and Tianjin Lingang Investment Holdings Co., Ltd. with a registered capital of RMB960 million.
